   Color
     --ink        #12191F  deep charcoal-navy (headings, footer, "&CO" black)
     --teal       #0A7AAA  brand teal, sampled from the logo mark
     --teal-deep  #075A78  pressed/hover teal
     --teal-mist  #EAF3F6  pale teal tint for section backgrounds
     --brass      #AD8A3F  muted brass — the "official seal" accent
     --paper      #FBFAF6  warm paper white (ledger page, not pure white)
     --line       #DDE3E0  hairline rule colour

   Type
     Display: 'Roboto Slab' — echoes the slab-serif of the wordmark
     Body:    'Manrope'      — contemporary grotesque, quiet workhorse
     Utility: 'IBM Plex Mono' — ledger figures, eyebrows, tracked labels

   Signature
     The "ledger-frame": an open rectangle with one notched corner,
     lifted directly from the logo mark. Used to frame the hero, section
     eyebrows, cards and images throughout the site — the one recurring,
     unmistakable device.
